While it sounds nice on paper, in reality its not that good talent. Most of your damage comes from Overkill ability, and Searing attacks has no effect on it. As for basic attacks, your attack range is limited and you can get kited around very easily. 5 seconds is a short window, so its only useful versus stunned enemies or structures. Besides, Rapid Fire does almost the same thing, but passively and indefinitely. So i’d say Rapid Fire is better option for you.

Conclusion for tier 3: Rapid Fire is the best option you have. Passive, gives a nice damage boots, great talent all around.

Ultimate Abilities:

Commandeer Odin Cooldown: 100 seconds Duration: 17.5 seconds Tychus pilots the Odin, gaining a second health pool and reducing the duration of Crowd Control effects by 50%. Basic Attacks in the Odin do not require a windup. Odin has the Raganrok Missile and Annihilate abilities.

Odin is pretty bad at this moment (24th march 2014). Damage output is pretty weak, abilities are quite weak, it doesnt last long enough and even the nuke upgrade for it barely does anything. I do not recommend taking this ultimate. While it looks badass, its quite useless.

Due to high attack speed of Tychus, this talent ability has its bonus reduced to 0.5% health. Again, most of your damage comes from overkill ability so your basic attacks dont matter that much. Besides, 0.5% is a really small bonus. Skip this talent.

Relentless Reduces the duration of silences, stuns, slows, and roots against your Hero by 50%.

While its a good talent, it loses competition to the other talents in this tier.

Lead Rain (Q) Overkill applies a stacking slow onto damaged enemies, slowing by up to 40%.

Doesnt work with overkill because it only applies to basic attacks. Take this only if your team has a lot of stuns/slows, like ETC for example. You dont have slows/stuns youself so you cant really make this talent useful on your own.
